Undertaker's Spade

Rites of rest are etched deep into the broken-off blade of a deceased gravekeeper's shovel. When used as a catalyst to cast an Impaling Spike spell, the blade disintegrates into dust, mixing with the earth and allowing the spell to damage incorporeal creatures as if it were a weapon imbued with a Ghost Touch property rune. An incorporeal creature can be Immobilized by a spike if it's adjacent to a solid surface when struck; it can attempt to Escape as normal but can't phase through the spike or escape to the Ethereal Plane.
